Barclay, Niles, Mich.,assignors to The Kawneer Company, Niles, Mich., a corporation ofMichigan v Application January 7, 1933, Serial No. 650,653 8 Claims.(C1. 189-'73) The present invention Aconsists in a novel wininterruptedsliding movement of the sash.

- are telesooping jamb sections 6 and 7, the under section 6 beingprovided with a web 8 having at its one edge spaced counter-sunkopenings 9 for the reception of screws, bolts orother attaching means 10for connecting the jamb structure vto the vertical supports 2 and 3, andat its other edge this web is provided .with a rearwardly facing channel11, the purpose of which will be later more fully explained. The centralportion of the Web is provided with oppositely extending ears o1x ribs1,2 forming channels 13 betweenthe samev and the web. These channels areadapted to receiv'e inwardly extending flanges or ribs 14 and `15 on thevjamb section 7 whereby these sections interengage and telescope so asto prevent lateral removal of one from the other.

Thus the jamb sections are interlocked and can be assembled or removedonly as a unit, although the sections may be engaged or disengaged by asliding longitudinal movement prior tov their rinsertion in the windowor after they have been removed therefrom. The outer portion 16 of thesection 7 forms a finish strip and is adapted to cover the openings 9and the attaching means 10 `for the inner jamb section to prevent thescrews or bolts from working loose and out. However, the section 7 isprovided with spaced openings 17 which, upon a raising or upwardlysliding movement of the section 7,'

may be brought into registry with the attaching means 10 so as to permittheir removal or attachment as desired.

The section 7 is further provided with a longitudinally extending rib orguide member 18 upon which the sash member 19 slides. This sash memberis provided with rails 20 each having an inwardly projecting glassrebate comprising spaced flanges 21, and outwardly projecting legs orflanges 22 provided with extensions 23, the ends thereof adapted to formshoulders for the reception of weathering means. The inwardly extendingflanges 21 are adapted to receive a rubber or other resilient retainingstrip 24 for holdingfthe glass 25. in position in the sash. Thisretaining strip 24 is provided with a rearwardly extending bead 25'*extending for substantially the entire periphery of the retaining stripas shown more particularly in Fig. 7, except for cut-out portions atcertain or all of the corners, these cut-out portions being for thepurpose of permitting overlapping of the webs 26 of adjacent rails. Thisconstruction is more clearly disclosed in Fig. 6 in which tlie web 26 ofthe upper rail extends beyond the ends of this rail and is bent inwardlyand attached to the inside of the adjacent or side rail 20 by anysuitable attaching means 27. By this construction, the adjacent railsare anchbred together and form a rigid sash construction. The

abutting outer edges of the rails may be joined in any suitable manneras by welding or the like.

. The outwardly extending legs or'iianges 22 of the side .rails 20receive and retaina weatherstrip 28 of carpet-like structure with thepile or nap thereof extending inwardly and. contacting the rib or guidemember 18 of the jamb; This weathering means by reason of the contact ofshocks to which the sash member may be subjected thereby maintaining thesash free from rattles, yet at the same time leaving the contactingsurfaces free from unnecessary friction in the operation of raising orlowering the sliding sash.

The outwardly extending legs or anges 22 of the lower sash rail 20 areadapted to receive a moulded rubber strip or resilient weather-strip ormember 29 providing aweathering means between the closed sash and thesill 4. The extensions 23 on thesev legs o'r flanges, as well as thoseon the side rails, provide suitable anchorage and retaining means forthe weathering strip on each of these rails.

In order to provide a weather-tight engagement between the frame and theupper sash rail 20, the head plate 5 of the frame is provided with alongitudinally extending (AI-shaped clip or retaining means 30 forholding a carpet-like weathering strip 31 havingv its nap or pile wip'-ingly contacting the outer surface of the upper sash rail 20. Thus thewindow is efiiciently weather-stripped on all four sides so as toprovide a weather-tight closure.

A latch member32 is mounted on'one or both of the side rails foranchoring the sash in any desired position. `Each latch member isprovided with a bolt orplunger 33 adapted to be operated .by a handle34, the plunger being adapted to seat within spaced notches 35 in a rack36. This rack is mounted on the jamb section 6, the attaching means 37therefor extending into the channel 11 in the back of this jamb section.Such attaching means may be screws, bolts or the like.

Although the window construction is shown as mounted in a bus orautomobile, it is to be understood that this structure is suitablyadapted for use in railroad coaches, Pullman cars, electric cars, or anyother conveyance in which a slidable sash may be provided and tightconstruction is desired.

Having thus disclosed the invention,

We claim:

In a window construction, a frame therefor comprising a jambsectionvadapted to be mounted in the window opening, attaching means foranchoringusaid section to the vertical supports defining said opening,and a jamb section engaging said first section and covering saidattaching means whereby to prevent such means from workingv loose andout.

4. In a Window construction, a frame therefor comprising a jamb sectionadapted to be mounted in the window opening, and a second sectiontelescopically engaging said iirst section and removable therefrom onlyby a longitudinal sliding movement, said sections being removable fromthe window as a unit.

5. In a window construction, a frame therefor comprising a jamb sectionadapted to be mounted in the Window opening, and a second sectiontelescopically engaging said ilrst section and removable therefrom onlyby a longitudinal sliding movement, a guide on said second section, anda sash slidable on said guide, said sectionsand sash being removable asa unit.

6. In a window construction, a trame therefor. comprising a jamb sectionadapted to be mounted in the window opening, attaching means foranchoring said section to the vertical supports defining said opening, asecond jamb section telescopically received on said iirst section andprovided with a guide, and a sash slidable on said guide, said sectionsand sash being removable as a unit.

'L In a window construction, a frame therefor comprising a jamb formedof telescoped sections adapted to be assembled and removed from thewindow opening as a unit, a rib on one of said sections, and a sashslidable on said rib, said sash being channelled for the reception ofthe rib and a carpet-like weathering in said channel and contacting saidrib for forming a. weather-tight closure.

8. In a metal window construction, a frame therefor comprising a jambformed of interlocked sections adapted to be mounted in and removedlfrom the window opening as a unit and prevented from being separatedfrom one another while positioned in the window opening, a guide on oneof saidsections, a sash adapted to receive said guide and slidablethereon, and a weather strip mounted in the portion of the sashreceiving said gide and provided with a l nap engaging said guide with awiping contact FRANCIS J.
